I ve just got a copy of the sims and the sims vacation, both discs contain a crack file and basically I dont know what to do to install them, help please.:confused:

Are they just .EXE files?
If so take the cracked EXE and find where you installed The Sims. ( It may be c:\program files\ea games\Sims or something like that). And look for a file named the same as the cracked .exe and just replace the cracked exe with the original one.
